ABOUT THIS DOCUMENT
This fax discusses the procedures for booting into Service
mode at AIX 4.1 for various RS/6000 models.
BOOTING THE 43P:
The 43P does not support booting off of an install tape.
For tapes, it only supports booting off of a 43P mksysb tape
with AIX 4.1.4 and SMS 1.07 or later. The only other accept-
able boot media for keyless machines when booting into
Service mode is an AIX Install CD. If your current bootlist
lists the CDROM or tape drive before the hard drive, you can
insert your boot media into the drive and restart your
system, from which point you can follow Step 2 of the Keyed
Machine instructions below.
If the CDROM or tape drive is not on your current bootlist,
you will need to alter your bootlist before proceeding
further:
1. Insert the SMS diskette in the disk drive.
2. Restart the system.
3. As soon as the first screen appears, press the F4 key.
This is after the keyboard icon appears on the screen,
but before the last icon appears. The System Management
Services screen will appear.
4. Choose "Select Boot Devices", and set the sequence for
boot devices to be read at boot time so that the CDROM
or tape drive is read before the hard drive.
5. Go back to the System Management Services screen, and
choose F3 to reboot once you have removed the SMS
diskette and inserted the bootable media into the appro-
priate drive. The system will begin to boot off the CD
or tape.
6. You are now in Step 2 of the Keyed Machine boot
intructions below.

BOOTING THE 850 (THINKPAD):
The 850 cannot boot from tape, only from an AIX Install CD.
Per the 850 instruction book,
1. Power off the system and wait 5 seconds.
2. Press and hold F1; then turn on the computer.
3. Keep holding down F1 until the Easy-Setup menu appears
4. When the EASY-SETUP screen appears, select the STARTUP
icon (shows a diskette, cdrom, hard drive, a question
mark, and the numbers 1 and 2) which lets you change the
order in which the computer searches for boot devices
for the operating system. CLEAR the current setting and
then select the cdrom for choice 1 and hdd (the hard
disk) for option 2. Select OK.
5. Insert the install CD in the drive, and then select the
EXIT icon. This should start the AIX boot process from
the CD or tape.
6. You are now in Step 2 of the Keyed Machine boot
intructions below.
BOOTING THE E20, E30, AND F30:
The E20 will ONLY boot from a mksysb or Sysback tape, not
an IBM install tape. If you don't have a mksysb or Sysback
tape, your only boot option is an AIX Install CD. If the
current bootlist lists the CDROM or tape drive before the
hard drive, you can simply insert your boot media into the
drive and restart your system, from which point you can
follow Step 2 of the Keyed Machine instructions below.
If the CDROM or tape drive is not on your current bootlist,
you will need to alter your bootlist before proceeding
further:
1. Boot the system and wait for the keyboard icon to
appear, then press F4 before the long beep.
2. To select a boot device or boot from a specific device,
change the StartUp option. Clear the bootlist and set
the sequence for boot devices to be read at boot time so
that the CDROM or tape drive is read before the hard
drive.
3. Insert the bootable media into the appropriate drive and
reboot. The system will begin to boot off the CD or
tape.
4. You are now in Step 2 of the Keyed Machine boot
intructions below.

BOOTING AN SMP MACHINE (G30, J30, OR R30):
The procedure for booting these three models are similar to
the standard keyed machines (explained below). The Key Mode
Switch on the front panel needs to be in the Service posi-
tion, or the Electronic Mode Switch needs to be set to
Service (while the physical Key Switch is set to Normal). If
the AutoService IPL flag is enabled, the system will boot as
outlined below. However, if the AutoService IPL flag is dis-
abled, you will be brought up to the maintenance menu. If
this happens, choose the SYSTEM BOOT option, then choose
BOOT FROM LIST. This will boot the system from the Service
mode boot list. You can then follow the normal Service pro-
cedures below.
BOOTING A KEYED MACHINE INTO MAINTENANCE AT AIX 4.1:
1. Turn the key to the Service position.
2. With BOOTABLE MEDIA OF THE SAME VERSION AND LEVEL AS THE
SYSTEM, boot the system.
The bootable media can be ANY ONE of the following:
o Bootable cdrom
o NON_AUTOINSTALL Mksysb
o Bootable Install Tape
Follow the prompts to the "Welcome to Base OS" menu.
3. Choose "Start Maintenance Mode for System Recovery"
(Option 3)
The Next Screen will prompt the "Maintenance" menu.
Choose option 1:
"Access a Root Volume Group"
The next screen will print a warning message and ask you
to select 0 to continue. Select 0.
"0 Continue"
The next screen will ask you to select the proper volume
group. Select the proper volume group for your machine.
The console will display information about rootvg, and
also display a Menu with two Options. Choose option 1:
"Access this volume group and start a shell"
If you get errors from the above option, do not continue
with the rest of this procedure. Correct the problem or
if you need assistance correcting the problem contact
one of the following:
o local branch office

05/30/96, 4FAX# 5256
o your point of sale
o 1-800-CALL-AIX (to register for fee-based services)
All of the above avenues for assistance may be billable.
4. Once the previous step is successful, enter the fol-
lowing command:
ODMDIR=/etc/objrepos
export ODMDIR
5. Set the TERM variable to match the terminal you are
using.
You will need to know the terminal type, such as "Lft"
or "ibm3151". To set the TERM variable, enter the fol-
lowing, replacing "" with the appropriate
value:
TERM=
export TERM
Setting TERM to the correct terminal will allow vi to
work properly.
6. When you are finished working in maintenance mode, turn
the key to Normal (eject the bootable media on keyless
systems), and run "shutdown -Fr" to boot back into
Normal mode.
